With the release of App Connect Enterprise 13.0.3.0, the new Embedded Global Cache has been introduced as a replacement for the older WebSphere eXtreme Scale (WXS) embedded cache, now referred to as the Embedded WXS grid. As outlined in the product’s statement of direction, the Embedded WXS grid is now deprecated, though it will remain functional as long as Java 8 continues to be supported in ACE.
Similar to its predecessor, the Embedded Global Cache allows you to store and reuse data across the same integration flow, between different flows, or even across multiple integration servers—removing the need for alternative persistence solutions like databases.
